Jetting is crucial on two strokes. I would bet this is the issue.. The carb just comes with one so that the hole isn't empty basically...no clue what jetting u need, but whenever u change a carb you need to reset...
Somebody more familar with a35's will chime in here on what jets you should get...
Be happy that you made this post before riding it, too small of a jet and you will seize your engine..
